SPVM::IntList - Dynamic int Array

IntList is a dynamic int array.
IntList
int
enum { DEFAULT_CAPACITY = 4, }
The default capacity. The value is 4.
4
has capacity : ro int;
The capacity. This is the length of the internally reserved elements to extend the length of the list.
has length : ro int;
The length of the list.
has values : ro int[];
The elements of the list. This is the internally used array, but it can be manipulated directly.
my $elements = $list->values; $valeus->[0] = 5;
static method new : IntList ($array = undef : int[], $capacity = -1 : int);
Create a new IntList object using "new_len".
The passed length to "new_len" is the length of the array. If the array is undef, the length is 0.
undef
0
The elements of the array are copied to the values of the the created array.
Examples:
my $list = IntList->new; my $list = IntList->new([(int)1, 2, 3]);
static method new_len : IntList ($length : int, $capacity = -1 : int);
Creates a new IntList object with the $length and the $capacity.
If the $capacity is less than 0, the capacity is set to the value of "DEFAULT_CAPACITY".
If the $length is greater than the $capacity, the $capacity is set to the $length.
Exceptions:
The $length must be greater than or equal to 0.
method get : int ($index : int);
Gets the element of the position of the $index.
The $index must be greater than or equal to 0.
The $index must be less than the length of the $list.
method insert : void ($index : int, $element : int);
Inserts an $element to the position of the $index.
The $index must be less than or equal to the length of the $list.
method pop : int ();
Removes the last element and return it.
The length of the $list must be greater than 0.
method push : void ($element : int);
Adds an $element after the end of the list.
method remove : int ($index : int);
Removes the element at the position of the $index and return it.
method replace : void ($offset : int, $remove_length : int, $replace : int[]);
Replaces the elements of the range specified by the $offset and the $lenght with the $replace array.
The $offset must be greater than or equal to 0.
The $remove_length must be greater than or equal to 0.
The $offset + the $removing lenght must be less than or equal to the length of the $list.
method reserve : void ($new_capacity : int);
Reserves the elements with the $new_capacity.
If the $new_capacity is greater than the capacity of the list, the capacity of the list is extended to the $new_capacity.
Note that "values" is replaced with the new values and the values of the original list are copied to the new values in the above case.
The $new_capacity must be greater than or equal to 0.
method resize : void ($new_length : int);
Resize the list with the $new_length.
The $new_length must be greater than or equal to 0.
method set : void ($index : int, $element : int);
Sets the $element at the position of the $index.
method set_array : void ($array : int[]);
Sets an $array. Each element of the $array is copied to the element of the list.
The $array must be defined.
The length of the $array must be the $same as the length of the $list.
method shift : int ();
Removes the first element and return it.
method to_array : int[] ();
Converts the list to an array.
method unshift : void ($element : int);
Inserts an $element at the beginning of the list.
